Directional photochemical processes with an amphiphilic anthraceno–ruthenium complex in dihexadecyl phosphate vesicles

Excitation of an amphiphilic anthraceno–ruthenium complex, which serves as an antenna-sensitizer complex, leads to two kinds of anthracene triplet states, one of which is bleached by a hydrophilic acceptor and the other by a hydrophobic acceptor in dihexadecyl phosphate vesicles; the latter process is directional from the surface to the interior of the bilayer membrane.
